Corrected entry: A well-documented bit of censorship involves Series 2, Show 6 (first broadcast 20/10/70). This show featured an animated fairy story where a prince finds a spot on his face. "Foolishly, he ignored it," informed Carol Cleveland as the narrator. "And six months later he died of cancer." Although this was originally transmitted intact, the BBC were worried, and insisted that the word "cancer" be replaced for a repeat showing in August 1971. The word "cancer" was thus replaced by the word "gangrene". Unusually for the series, the word 'gangrene' does not appear to be voiced by any of the Python team themselves. To underline the fact that the word "cancer" had been replaced (and as a protest against the censorship?), a male voice replaces Carol Cleveland's narration for this one word only.

Correction:This does not count as a goof, especially given the nature of Pythonesque comedy. The canned laughter that follows the blatantly obvious redubbing should be a giveaway.

Kenny Lust: Good evening, ladies and gentlemen, and welcome to the refreshment room here at Bletchley. My name is Kenny Lust and I'm your compère for tonight. You know, once in a while it is my pleasure, and my privilege, to welcome here at the refreshment room, some of the truly great international artists of our time. And tonight we have one such artist. Ladies and gentlemen, someone whom I've always personally admired, perhaps more deeply, more strongly, more abjectly than ever before. A man... Well, more than a man, a god, a great god, whose personality is so totally and utterly wonderful my feeble words of welcome sound wretchedly and pathetically inadequate. Someone whose boots I would gladly lick clean until holes wore through my tongue, a man who is so totally and utterly wonderful, that I would rather be sealed in a pit of my own filth than dare tread on the same stage with him! Ladies and gentlemen... The incomparably superior human being, Harry Fink!Man: [from offstage.] He can't come!Kenny Lust: Never mind, he's not all he's cracked up to be.

In the Marriage Counselor sketch, Deidre Pewty is wearing such a tiny miniskirt that when she sits we see she is wearing white knickers. When she undresses behind the screen she throws a pair of black knickers out.
